No pen, back to Q-tip, but use gunmetal bluing/blacking... after bopping yourself upside your forehead.

"Blueing" is a rusting process on steel which won't work on non-ferrous metals, and some stainless alloys. WAY ahead of you.
I was thinking along these lines... not old school "blueing", though I guess I should have been more specific, my bad.

• Room temperature chemical
• Used by gunsmiths and industry to blacken aluminum parts
• Restores scratched & marred areas quickly
• Color will vary from deep gray to black depending on the alloy


last time I used that, I got medium gray after about 5 layers. Might try again, as this is a different alloy.
